Log message:
Just define PKGNAME and use it.

Log message:
Mark as meta-package.

Log message:
* If PLIST_SRC is explicitly set to an empty value in a package Makefile,
  then automatically generate a PLIST that says "${PKGNAME} has no files".

* If PLIST_SRC and GENERATE_PLIST are not set in a package Makefile,
  and no PLIST files exist, then fail during the package build with
  PKG_FAIL_REASON.

* Remove "intentionally empty" PLISTs again.

Now, the easy way to say that a package installs no files is to just
add the following to the package Makefile:

	PLIST_SRC=	# empty

Log message:
Re-add "intentionally empty" PLISTs for meta-packages and other packages
that directly manipulate empty PLISTs.

Modify plist/plist.mk so that if the PLIST files are missing and no
GENERATE_PLIST is defined, then the package fails to build.

Log message:
Remove empty PLISTs from pkgsrc since revision 1.33 of plist/plist.mk
can handle packages having no PLIST files.

Log message:
Whitespace cleanup, courtesy of pkglint.
Patch provided by Sergey Svishchev in private mail.

Log message:
Allow the binpkg-cache script to also generate pkg_summary.gz files
if requested.  Suggested by Joerg Sonnenberger.

Log message:
Replaced "# defined" with "yes" in Makefile variables like \ 
GNU_CONFIGURE,
NO_BUILD, USE_LIBTOOL.

Log message:
Drop distinction between PKGSRC_USE_TOOLS and USE_TOOLS by making
PKGSRC_USE_TOOLS go away.  There is now only a single USE_TOOLS variable
that specifies all of the tools we need to build/run the package.

Log message:
add find to the tools list
